What they do.

PBM Pharmaceuticals’ primary product was Donnatal, an adjunctive therapy used in the treatment of irritable bowel syndrome (“IBS”) and acute enterocolitis.


PBM purchased the Donnatal brand in the 1990’s and operated the business until 2012 when he sold the business to Concordia (TOR:CRX) for a combination of cash and stock that totaled $400 million.

Achievement of note:

PBM hired, trained and oversaw a marketing and sales team of 100 people that helped grow the Donnatal brand from $2 million in sales to over $50 million.

How they’re improving the quality of people’s lives:

Irritable Bowel Syndrome, which affects over 35 million people, is a chronic, often debilitating, functional gastrointestinal disorder with symptoms that include abdominal pain, bloating and altered bowel behaviors. Donnatal has been providing decades of relief for people suffering with IBS, enabling them to live a more normal life.
